l .a citizen of the United States, residing in I Middletown, Connecticut, have invented a. new and useful Improvement in. Mats, of

which the following is a specification. Thisinvention is designed to facilitate the fmakihg and cheapenthe cost of manufacture jof those metallic-mat constructions which embrace a mat body comprising strips of metal corru borderor'frame.

. cured to the bars or rods of the border By practice the body-strips are ,each made of a 2'15 engthsubstantially e ual to the length of the mat, While each si e and end edge (collectively forming'the .nrat-border) is formed from one or more straight rods or bars connected at'the corners of the mat by separate '20 angl'eor corner piecesrivetedor otherwise sequire, therefore,fto be bent back upon themselves at the ends of the mat and the end poringa comparatively long ro or bar 'lnterrnetions of the contiguous strips properly assembled with eachother. amalso enabled to avoid thetime-consuming o eration of bonddiate its ends to form a mat-corner, since the separate anglejor corner pieces being of rela-.

tively short linear. dimension are readily struckup inapressy 1 Inthe' drawings accompanying this speci-' fication, Figure 1 is a plan view of amat embodying'my resent lmprovements, the scale of the figure eing somewhat small. Fig. 2 is a plan view of a 'corner ofthe mat of Fig. 1, the "scale of the f figure being somewhat enlarged, j Fig. 3 is an edge viewof Fig 2. I

I p Similar; characters of reference designate corres ending parts'in all the figures. I 1

,Int e particular mat chosen for illustra u tion and the-manufacture of which is facilitated andc heapened when the presentimprovements are employed therein the body I portion'of the'mat com rises a numberof strips 2, each corrugate transversely of its gated or otherwise and asuitable 1 In carrylng the'presentimprovementsinto "-YQBK, EXECUTORS 0E SAID MARTIN, DECEASED If MAT;

the mat, as contrasted with agreater length,

and which would require a bendingv operation to be performed to; bring the strip back upon itself. I also avoid any necessity for properl y assembling the contiguous ends of such reverselybent strips, thus adding to the fa-' ,cility and cheapness of cost involved in manufacture. The stock. of the mat-border is here of half-round hollowed-out shape, and the border comprises, according" to the present improvements, a rod; or bar 3 ateach side of the mat, as well as a similar rod or bar at each end of the mat. Imean, of course, in statingthat a single rod forms an edge of the mat that saidvedge may be made of two or more pieces placed end toend and secured in such relation. one edge of the mat-border is connected with an end-forming r'odby an independent angle or cornerforming piece 4,'riveted, as at5, or otherwise secured to the mentioned rods.

There are four of these separate corner-form ing pieces, and they maybebent to a curve,

'. as indicated, or'otherwise struckup, as desired. By making the mat-corners of ieces v separate from but secured to the mat e gas I a compara-' avoid the necessityof striking tively long rod or bar interme iate its ends (an awkward I operation) and substitute therefor a bending operation upon a comparatively short piece whose-legs are of substantially the same'length and the forming of 'which involves a step inmanufacture more readily accomplished than that represented by the bendingof a comparatively long piece.

ApplicationfiledTune2'7,1905/S1ia11l0.267,190 v i In order to firmly attach the ends of the,

body-strips to the border, l may adopt the construction illustrated, in which each strip is perforated ;adjacent to its ends, and

through the perforations end rods 6 are passed, these rods beingpreferably secured to the mat-border by riveting over'the ends of the rod, as indicated, while the rod also passes through eyes 7, whose shanks 8 are rivetedto the end rods of the border. Transverse strengthening-rods v8, passing through openings in strips 2 and riveted over-the side rods of the border, are also indicated, as .well' too as longitudinal strips9, placed on edge and extending fromend to end of the mat.;

A constructionsuch as that indicated less-' ens the manual operation necessarily insaid rods; and whose shanks are secured to the contiguous length of the mat-border, and relatively transverse strengthening-rods extending between the parallel ends and the parallel sides of the mat-border.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
